REFRIGERATOR Application filed July 25,

' a current of air.

This invention Comprises the novel mechanism and combinations hereinafter described and more particularlypointed out and defined in the appended claim.

In the'accompanying drawings, which illustrate a preferred embodiment of this in- 'vention, and in which similar reference numerals refer to similar features in the differ-- eut views:

Figure l is a fragmentary elevational view of the novel form of refrigerator with the door of the cooling chamber cut away.

Figure 2 is an enlarged sectional view through a row of cooling tubes with an air blast pipe in elevation and located therebeneath.

Figure 3 is a horizontal section through the cooling chamber upon an enlarged scale upon the line 33 of Figure 2.

Figure 4 is anenlarged sectional view through a pair of cooling tubesand the air blast pipes.

Figure 5 is a horizontal section through the cooling chamber taken substantially on v the line 5.-5 of Figure 2 upon an enlarged scale.

As shown on the drawings:

In the specification .of this invention there is illustrated a refrigerator having a cooling chamber 1 formed therein which is adapted to cool the compartments in which articles are kept, one of such compartmei ts being illustrated in Figure 1 as closed byfa door 2.

Within the cooling chamber, a bank of vertical tubes 3 are located. The lower ends of these tubes are soldered or secured in the top of a substantially closed casing 4, and the upper ends of these tubes extend some distance into a 'water or fluid contain- 1822. Serial No. 577,282.

they are interiorly lined with some fibrous material 6 susceptible of strong capillary action. This material (3 may be in the form .of tubes fitting within the tubes 3 and folded over the upper ends of said tubes 3 that project into the fluid container 5 so as to become immersed in the fluid, which is usually of shallow depth in the container and necessarily below the top of thetubes 3.

Below each longitudinal row of tubes 3. there is an air blast pipe 7 closed at one end and provided with a plurality of spaced tuyeres 8 corresponding to the spacing of the tubes 3 and located directly therebeneath. The open ends of these pipes 7 are coupled or connected pipe The pipes 7 and the air distributmg pipe 9 are located in the vcasing 4, and an air supply pipe 10 extends through an aperture in the end ofthe casing 4 and is connected or coupled to the air distributing pipe 9. The air supply pipe 10 comprises a number of sections coupled together, with the upper section secured to a rotary blower 11 or the like which is operative'ly connected to a motor 12, both of which may be located on the top of the refrigerator,

The operation of the blower .will force blasts by means of the. pipe 10 through the tuyere pipes .7 which will direct the air throughthe bank of cooling tubes 3. As the lining of these tubes dips into the fluid inthe' container 5-, the fluid, which is pret erably water, will be drawn up by capillary to an air distributing attraction for moistening the said lining,

and as the blasts of air rush through these cooling tubes, the moisture in the linings Wlll evaporate. It is, of course, well known that heat units are consumed in this evaporation process with the consequent result of lowerin the temperature. The spent air blasts wil escape from the cooling chamber through an exhaust or discharge pipe 14:. It will be apparent that the rotary blowerwill maintain a continuous circulation of air through the cooling chamber so that the latter Wlll always remain cool and ,in a good state of refrigeration.

I am aware that numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not pub pose limiting the patent granted otherwise than ncessitated by the prior art.

I claim as my invention K In 1i refrigerator, a cooling chamber, :1

bank'of ooolil'i tubes located therein, on up-- per mclosed %u1d containing easing into which Siillli tubes extend, a lower casing in upper casin museum which said tubes are seourd, tuyre pipes arranged in said lower casing under said tubes, means for conducting fluid from said into said tubes, and means for forcing air Enough said tuyre pipes.

In testimony whereof I have hereunto subscribed my name.

CHARLES H. EVANS.
